Flour & Food

Problems faced by the Flour/Food Production industry.

Hygiene within food manufacturing plants and bulk storage facilities is obviously critical and washing with water can lead to mould growth. Intermittent cleaning can lead to batch contamination when older material dislodges and mixes with more recent batches.

Dry particle build-up and blockages

Due to the nature of the industry, particulate build-up and blockage is especially common due to the texture of flour and processed food materials. The dust matter gets spread around with little effort, causing walls of production equipment/surfaces to become coated in powdery particles. To maximise production and reduce plant downtime, rigorous cleaning procedures must be in place to remove such dusty substances.

Product contamination

Within flour/food production plants, the properties of the air (mainly temperature and humidity) are controlled to prevent or reduce the growth rate of some microorganisms in manufacturing and storage areas. Particle content is controlled to limit the risk of product contamination and promote safe food manufacture.

Guidelines on air handling in the food industry

It is a requirement of food manufacturing guidelines to make sure that the quality of air within manufacturing plants is strictly controlled. Environmental air of a specified temperature, humidity, particle concentration and quantity is legally required for the comfort and safety of employees.

Dust control for the food industry serves 5 major purposes:

  • To protect the operator from inhaling fine particles.
  • To prevent dust spreading in process areas and causing cross-contamination.
  • To prevent accumulation of dust which may provide a substrate for growth of microorganisms.
  • To prevent environmental pollution.
  • To prevent explosion.

This is why it is especially important to combat particulate build-up within plants, and by doing so, you are not only enhancing the health and safety standards of your factory, but you are reducing unscheduled plant shut-down times. Primasonics’ Acoustic Cleaners prevent dust build-up within ducts and air handling units through their acoustic technology.

How Primasonics Acoustic Cleaning Solutions can help.

As the food manufacturing industry continues to grow to accommodate the demands of the modern person’s busy lifestyle, food producers and engineers strive for continuous improvement to their plants in all kinds of forms – whether this be a reduction in unnecessary downtime, labour or costs. One way to do this would be through the introduction of our Acoustic Cleanings solutions.

Primasonics Acoustic cleaners can be placed in blenders, spray dryers, silos, ductwork and filters within your flour/food production plant to prevent material adhering to process vessel surfaces and therefore maintain clean free flowing surfaces. They are manufactured to the highest food grade standards and are easy to retrofit


  • Target excessive material buildup.
  • Improve material flow.
  • Lower operating costs compared to alternatives.
  • Prevents unscheduled downtime.
  • Extended plant life.
  • Easy to operate.

Acoustic Cleaning Solutions prevent build-up of particulate matter and blockage within production equipment that would eventually go out-of-date – thus avoiding the need for a thorough, deep-clean which helps to avoid unscheduled maintenance expenses and

They are the perfect alternative to cleaning practices that require strong detergents and potentially harmful disinfectants that are required to prevent bacteria but could infect the products. This way, they promote increased plant productivity, safety and even greater staff well-being.

The science behind Primasonics Acoustic Cleaners.

The process encompasses the realm of sound transmission through solids. It is best described by the creation of rapid pressure fluctuations. Lower frequencies produce higher levels of displacement.

These pressure fluctuations are transmitted into the particulate matter or “bonded” dry production material causing the solid particles to resonate and dislodge from the surface they have bonded to. Once dislodged, the materials fall, either due to gravity or are carried away by the gas or air stream within the process.

The technology can increase the efficiency of process plant, provide improved thermal conductivity, prevent material blockage and remove particulate build up wherever ash, dust, powders or granular materials are processed, generated, stored or transported.
